The spot of adhesive II or its equivalent may be positioned to ContactV the surface of portion 3 of the blank below the edge of the flap 4 or it may be positioned to ad-v open when ilap 6 is opened. l l v To facilitatemanufacture of the envelope the fold lines of the blank may be in the-form of the' usual creases or scores to facilitate folding.: The

This modification-of the Venvelope also shows. a line of severance I3 so disposed as toprovideffor severanceo'f 'the uppenedgefoiY portion 5-along with'flap Gr'and thus to-clea'r/ apertures 'I when they extendbeyond the fold' line'ofk flap'4` into f,

f FigsG and '7 illustrateistill a further -modi'ca-` tion of-the =envelope showninlFigsl to in that Y the sifting openings 'I'are spaced from the .side i" edges'lof the envelope Yand the flap 4 is heldfin closedposition bytwofspots of adhesive I4positioned laterally of said openings. The purpose:

'ffthi'sarrangem'ent is .toavoid the possibility of hereto flap 4 provided the latter is fasteneddownv i sufliciently securely that it will not be .pulled`l "from moisture or contamination. This outer protective envelope may be made of paper or equivalent material and waterproofed if desired and may beofany desired construction, that is, the bottom' 'maybe sealed by folding the walls of fthe envelopefalong with the bottom closing flap as described in connection with Figs. 1 to 5 incluu sive, and the top maybe similarly closed. The

outer` envelopevrnay be designed to be opened by simply'tearing ofi the end but I prefer to use an envelope Joff'the` easily openableltype. `Most of such envelopes;V however.: are not completely sealedandl have provided an outer venvelopeV construction which' is .of theeasilyopenable type l. and is at the 'same time completely sealed.

Referring to Fig. 8 it will be seen that the -u'p-v per end of therenvelop'e is closed by folding over the wallsof the envelope atthe folding-eline I5 along with the flap l5 and that the apil 'is secured in closed' position by a strip I6 of material similar to. blotting paper the internal's'trength of Whichis suchxthat when itsioppositerfaees are glued .to Vthe-inside of the flap I4 and the front Wall II` of ,the envelope B, respectively, and the flap I5.i s pulled open,jthe stripflG will split, part of it remaining gluedlto the-'flapV I,5.at1d part of itV remainingvglued ito the front'wall Il' of .the

envelope. The front wallI'I of the envelope is cutaway at I'leaving the ears I9, I 9,'the intermediate portionv 20 .of the envelope -constituting the throat. 'I'he strip I6 is so dimensionedgand positionedthat its onefsurface clears thethroat l''portion'2Il1ofthe-front walll'l-but extends o ver obstructing-the openingsin the'event that the adhesve'should be stronger than the. paper and should split the paperV of the flap 6' or' the flap 4 and pull avsliv'er thereof whenilap 6 s'pulled open as might occur inthe embodiment illustratedln Figs. 1 to A5. In the'modication illustrated in Fig.`6, if a sliver of paper should be pulledto# L Ward the Vfoldingline I2when flap B' is Vpulled open itv would not be likely tofobstruct the openings 'I due to thelateral-spacing I4 from the openings 1;

' Irl the modification illustrated in Figs. V63nd '7 it hasbeen found to be advantageous to color-the of the `glue spots flaps4 andY l'Y 'differently'so that the free Aedge ofr the nap' 6 readily maybe seen and so that there` the ears I9,I9 thereby effectively sealing the end 'of the envelope when the nap I5 is in closed posi-v tion. When the flap I5 is pulledopen that part Vofthe stripIG which adheres to the flap Iand thegears I9, I9, continues to bind the ears I9, I9, but. the-throat portion 20 ofthe envelopebetween the ears I,9 I9- is opened for the removal of the inner envelope VA.- .As will be' appare-nt, th'e'inner envelope AV should-be and is somewhatnarrovverthan the outer envelope BJ. ait-.isof such aA widthY that.V it rea iilygrn-.yA beV withdrawn from VtheenvelopeBthrough thethroatl. y Y

the. complete `In :operation it will be seenthat packageillustratedin. Fig. 8 may be held in the leitghand, thevlap -Iy pulled open by thellngers of the right hand Aand the inner `envelope A extracted by means Ao a pair of sterile ytweezers or may be no fumbling or delay in, for instance, tryf y ing kto raise the vedge of the nap 4 which is firmly held to theouter surface' of portion l ofthe envelope.-

. It :will be the location of theaperturesf'l.. If they are centered in the fold vline of'flap 4 then portion IY should be cut away at 8 and the line of severance Y understoodfvthat the location of the i line of severance for flap 6 or I'lwill depend upon should be located as shown in Fig. (5 in order to v leer the Qpenineson both sides of the .fold-.line

` If the apertures are whollyrin the flap 4- then 'it :.may .Simply be .dropped 011ik by. inverting the package. nThe outer surface oilenvelo-pe B'is not sterilandthis operation may beperiorrned by one vvvl'iose hands" are not.sterile but' the sterile inner'e'nvelope Willthus be delli/'credito the person (doctorg' fsurgeonzor inurse)` whose Yhands are sterile, in :a (sterile. *condition' The doctor may then hold envelope A in hi'sleft 'hand while the i'ingersof his' right hand 'are used' to open nap 6 or' I5Y and, Yif desired, teaitfoif, along; the" line of severance I3. '.Env'elope iL-thus havingl been opened, is'ready foizuse' for dispensing 'the'con tained material through. the apertures 'i .without contamination. At thel same timev `thel sterilef technique Vof rthe surgeon; d'cctororvnurse is not broken, i. e. his or her hands will not be contaminated by their contact with the sterile inner envelope and they will not have touched the outer A envelope. The package of Fig. 8 having the inner and outer envelopes is more particularly designed for surgical use in which two persons normally willhandle the package, one Whose hands arenot sterile and the other Whose hands are sterile.
